Dingxin mechanical digital lock

Mechanical safety box digital lock with curve codes (1) Dingxin mechanical digital lock initiates a brand new digital disc and a linkage part and designs a more reasonable and accurate dynamic positioning structure, which can set a digital disc combination to 5 to 10 discs or more code discs, and a tens million to tens billion of codes can be set. (2) Convenient and reliable link control tuner is initiated, which cuts off the air between a code match system and an open-close system and realizes the link control sequence of firstly code match, secondly decode and then unlock. Therefore, code stealing and technical unlocking can be avoided. (3) Dingxin mechanical digital lock initiates the digital disc combination of curve codes and the curve lock snap-gauge combination, which can make all the lock latches in the digital disc combination change in the manner of any curve change within 360 degrees of circumferences as the setting manner of codes. The combinations on the curve lock latch can be combined anyway in parallel or series by single stage or multiple stages, and the arm length of the curve lock latch can be changed according to the actual needs, which realizes any combination of tens billion of curve codes and tens billon of digital codes in the digital disc combination. The lock forms the most advanced compound code setting manner at present, which avoids technical unlocking, and therefore, the safety of digital locks is enhanced innovatively. (4) The most advanced technique for the mechanical digital lock to set codes quickly all in zero positions within 360 degrees of circumferences on the digital disc is initiated. Users can set codes easily and quickly according to their preferred digits, and however many digital discs, two familiar digits to the user can be set (three or more digits are suggested). The set codes can be remembered easily and difficult to forget, and the codes can be matched easily and quickly. (5) The tuning disc with concave protective sheath is initiated, which can sink into the steel protective sheath completely, and the structure can not be pried, or drawn by external force, or damaged by pressure. (6) The link code disorder device is initiated, which can disorder all the set codes at the moment when the safe is closed and avoids a hidden trouble (the technique can be set according to the actual requirements of users). (7) Dingxin mechanical digital lock uses the optimization method as the theory, which initiates the code setting of the mechanical digital lock within 360 degrees of circumferences by memory insulation. The code match manner is characterized in that no scales or digits are displayed (four-direction, eight-direction or sixteen-direction coordinate scales can be set according to the actual needs of users), and the users do not need to worry if the set codes are known by others. If the user operates when opening or closing the lock in public, the operation can be done in public, which is suitable for jewelers and the cashier’s in the markets. The lock needs no keyhole, and needs no key or light when opening the lock. The lock can be locked and unlocked easily and accurately, and can be a match to electronic locks. (8) The codes can be changed easily and accurately. The codes can be set on the 360-degree circumference with no dead corner, and the number of turns can
